Description

Formwork joints with improved fixed performance and applied to areas where beams are larger than columns The present invention relates to a formwork joint with improved fixing performance, applicable to locations where the beam is larger than the column, which shortens the construction period and improves construction quality by rapidly and smoothly processing the process of connecting a concrete column smaller than the beam and a formwork for a horizontal member. Generally, in the formwork construction process at a construction site, reinforcing bars are placed on the floor surface and foundation concrete is poured over them. Then, vertical and horizontal reinforcing bars are arranged in a grid pattern connected to the aforementioned bars, and the reinforcing bars are bound together at their intersection points using thin wires before the formwork is installed. These conventional formworks require carpenters to cut and process plywood and lumber according to the blueprints on-site to create the formwork, pour the concrete, and then dismantle the formwork after curing. As a result, most of the formwork is damaged during the dismantling process, making it impossible to reuse and instead resulting in a double burden of having to be disposed of as waste. For these reasons, the increase in materials and construction volume required for formwork construction acts as a factor causing not only an increase in construction time but also an increase in construction costs. Meanwhile, formwork is classified into formwork for horizontal members, such as beams or slabs, and formwork for vertical members, such as columns or walls. Even in this case, since columns and beams must be installed and connecting members using plywood and lumber must be fabricated on-site to connect them, formwork for vertical members carries the risk of extended construction periods due to shape discrepancies between the formwork and the permanent structure (corresponding to formwork for horizontal members). In particular, in the case of formwork for vertical members where the beam is larger than the column, installation itself is difficult, which frequently causes delays in the construction schedule. FIG. 1 is a drawing illustrating a state in which a formwork joint with improved fixing performance is provided on a concrete column and a formwork for a horizontal member is connected, applied where the size of the beam of the present invention is larger than that of the column. FIG. 2 is a combined perspective view showing a formwork joint with improved fixing performance, applied where the size of the beam of the present invention is larger than the column. FIG. 3 is an exploded perspective view showing a formwork joint with improved fixing performance, applied where the size of the beam of the present invention is larger than the column. FIG. 4 is a drawing showing another embodiment of a face-forming part among the components forming a formwork joint with improved fixing performance, which is applied where the size of the beam of the present invention is larger than that of the column. FIG. 5 is a cross-sectional view of a key part according to another embodiment of a face-forming part of a formwork joint formed with improved fixing performance, in which the size of the beam of the present invention is applied where the size of the beam is larger than the column. FIG. 6 is a drawing showing a formwork joint with improved fixing performance, applied where the size of the beam of the present invention is larger than the column, mounted on a vertical member type formwork.
